Description

Big displacement lifting linking member formula auxiliary support mechanism

Technical field

The present invention relates to a kind of supporting mechanism, a kind of liftable branch used during arm discharge is in particulard relate to Support mechanism.

Background technology

In weapon heat emission technical field, product is during storage and transport, it is desirable to have auxiliary body is in appropriate position Put and product is supported, it is ensured that the distribution of product load, which is met, to be required, accordingly, it would be desirable to which auxiliary support mechanism is supported in position Product, and bear the fractional load of product.For some products, auxiliary support mechanism also needs to meet claimed below:

(1) requirement in space is got out of the way when product is supported when being risen to meet, being fallen, auxiliary support mechanism is needed to have along vertical Nogata to the steady elevating function of big displacement.

(2) it is the support product for meeting bearing requirements, ensureing Auxiliary support safety and stability, auxiliary support mechanism needs to have Larger bearing capacity.

(3) to meet compact conformation and requirements of installation space, auxiliary support mechanism while big displacement lifting is realized, its Physical dimension should be as small as possible.

(4) it is general from disc spring is as carrying product and provides reaction of bearing, to realize product for auxiliary support mechanism The vital part of buffering and vibration damping, and disc spring decrement is then the core parameter of Auxiliary support.Can be real to meet actual compression amount When the requirement observed, it is desirable to have the structure that disc spring decrement can be made visual.

Conventional auxiliary support mechanism is usually stationary structure, can adjust vertical position by adjust pad small range, The requirement of the overall big displacement lifting of Auxiliary support can not be met, specifically:

(1) because adjust pad size is smaller, conventional auxiliary support mechanism can not realize that vertical direction big displacement is lifted Function, therefore it is impossible to meet use requirement.

(2) using general elevating mechanism realize big displacement lifting often cause structure excessively elongated and stiffness not Foot, causes bearing capacity not enough, therefore it is impossible to meet bearing requirements.

(3) conventional method for driving fixed structure formula auxiliary support mechanism to be lifted using oil cylinder or electric pushrod can be led Cause mechanism vertical oversized, therefore it is impossible to meet requirements of installation space.

(4) Auxiliary support carries out disc spring compression measurement using simple and easy methods such as measurement plasticine deflections in the past, can only The disc spring decrement at circumstantial evidence a certain moment, does not possess the ability of real-time monitored disc spring decrement, thus decrement can not be met can Observation is required.

In summary, it is necessary to a kind of new auxiliary support mechanism can not only secure support product, and meet have it is big Displacement elevating function, possess that larger bearing capacity, vertical size are small etc. to be required.
